This is a very nice Combo, indeed!
It is coherent with the Vintage look of the Polaris, and with the thickness of the watch.
I went this way with my latest Polaris straps ( 4 mm thick ).
As for the OEM strap, it is interesting, but I think we may find better.
A Tropic, for example, or a Nato ( Nylon or Leather ), a distressed leather strap, there are so many possibilities!
Thanks for sharing, and congrats, my friend!
